List values, shorthand flag with more than 1 character values

[flyfishMT]

I am having some issues, I may just not understand how this works. This is on windows 10.

Lists

program
.option('-c, --components <components>', 'List of components to create')
.parse(process.argv);

Test
index.js --components dir\one dir\two

Expected results:
program.components = ["dir\\one", "dir\\two"]
Actual:
program.components = "dir\\one";

Shorthand flag, more than one character:

program
  .option('-tf, --testfolder [testfolder]', 'Description')
  .parse(process.argv);

index.js --testfolder somefolder
Results
program.testfolder = "somefolder"

index.js -tf somefolder
Results
program.testfolder = undefined

However, with a single char:

program
  .option('-x, --testfolder [testfolder]', 'Description')
  .parse(process.argv);

index.js -x somefolder
Results
program.testfolder = "somefolder"

1. List: I think this may take a coercion to declare and turn the option parameter into an array. For example:

function splitComponents(val) {
  return val.split(',');
}

program
  .option('-c, --components <components>', 'List of components to create', splitComponents)

and call like:

node index.js --components dir\one,dir\two

2. Short flags are a single character, with single leading dash. Multiple flags may be combined as mentioned in the README:

Short flags may be passed as a single arg, for example -abc is equivalent to -a -b -c.

3. You asked about options, but on a related note about arguments, the last argument may be a variadic argument

See also #913 for some other approaches to options taking lists.

An answer was provided, and no further activity in a month. Closing this as resolved.

Feel free to open a new issue if it comes up again, with new information and renewed interest.

Thank you, this was great help. Sorry for not posting back and closing.

FYI, there is a recent issue asking to allow multiple character short options: #2307
